Home Network Setup, Part 6

Heya,

Well I had this sitting in my drafts for quite some time and thought I’d be best to publish this immediately purely to get it out the door as quickly as possible.

Setting up JFFNMS

Firstly I add the Dag Wieers archives to the servers yum configuration.

/etc/yum.repos.d/dag.repo:

[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el4/en/$basearch/dag
gpgcheck=1
enabled=1

I then import the GPG key:

[root@dione yum.repos.d]# rpm –import http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt
Now that we have Dag Wieers archive setup it’s time to install a bunch of prerequisites:

[root@dione ~]# yum install mysql-server php net-snmp php-snmp php-gd php-mysql graphviz fping nmap rrdtool php-rrdtool

[root@dione ~]

Next we fix a few permissions for JFFNMS:

[root@dione ~]# chmod +s /usr/bin/nmap
[root@dione ~]# chmod a+x /usr/bin/nmap
[root@dione ~]# chmod a+x /usr/sbin/fping
[root@dione ~]# chmod +s /usr/sbin/fping

Next I had to make the following modifications to /etc/php.ini:

register_globals = On
error_reporting = E_ALL & ~E_NOTICE
include_path = “.:/usr/share/pear”

Next we setup some groups and users for JFFNMS:

[root@dione ~]# groupadd jffnms
[root@dione ~]# useradd -g jffnms -d /opt/jffnms -s /bin/false -c ‘JFFNMS User’ jffnms
[root@dione ~]# usermod -G jffnms apache

Next we download and extract our JFFNMS installation:

[root@dione ~]# wget http://optusnet.dl.sourceforge.net/sourceforge/jffnms/jffnms-0.8.2.tar.gz
–03:36:36– http://optusnet.dl.sourceforge.net/sourceforge/jffnms/jffnms-0.8.2.tar.gz

[root@dione ~]# tar -zxf jffnms-0.8.2.tar.gz
[root@dione ~]# mv jffnms-0.8.2/* /opt/jffnms/

Next we fix ownerships:

[root@dione ~]# chown -R jffnms:jffnms /opt/jffnms
[root@dione ~]# chmod 770 /opt/jffnms
[root@dione ~]# chmod -R ug+rw /opt/jffnms

Next we load the crontab jobs:

[root@dione jffnms]# crontab -u jffnms /opt/jffnms/docs/unix/crontab

Now it’s time to initialise our MySQL database. I need to change the root password first and setup the MySQL user and database:

[root@dione jffnms]# service mysqld start
Starting MySQL: [ OK ]
[root@dione jffnms]# chkconfig –level 345 mysqld on
[root@dione jffnms]# mysqladmin -u root -p password ‘123456’
Enter password:
[root@dione jffnms]#

[root@dione jffnms]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 3 to server version: 4.1.12

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the buffer.

mysql> CREATE DATABASE jffnms;
Query OK, 1 row affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON jffnms.* TO jffnms@localhost IDENTIFIED BY ‘123456’;
Query OK, 0 rows affected (0.01 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql> quit
Bye
[root@dione jffnms]#

Now we import our database:

[root@dione jffnms]# mysql -u jffnms -p jffnms < /opt/jffnms/docs/jffnms-0.8.2.mysql Enter password: [root@dione jffnms]#

Next we create a virtualhost for Apache:

/etc/httpd/conf.d/vhost-jffnms.conf
ServerAdmin stuart@seekbrain.com
DocumentRoot /opt/jffnms/htdocs
ServerName nms.seekbrain.com
LimitRequestLine 20000

And restart Apache:

[root@dione conf.d]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ]
[root@dione conf.d]#

Now it’s possible to goto nms.seekbrain.com and finish configuration.

I’ll get through to the final Part of this Home Network setup cleaning everything up as much as possible.
